-- Infers a schema by evaluating sample records on the specified streaming
-- source (Amazon Kinesis stream or Amazon Kinesis Firehose delivery
-- stream) or S3 object. In the response, the operation returns the
-- inferred schema and also the sample records that the operation used to
-- infer the schema.
--
-- You can use the inferred schema when configuring a streaming source for
-- your application. For conceptual information, see
-- <https://docs.aws.amazon.com/kinesisanalytics/latest/dev/how-it-works-input.html Configuring Application Input>.
-- Note that when you create an application using the Amazon Kinesis
-- Analytics console, the console uses this operation to infer a schema and
-- show it in the console user interface.
--
-- This operation requires permissions to perform the
-- @kinesisanalytics:DiscoverInputSchema@ action.
